Abstract

In this paper the linearity performances of harmonic tuned microwave power amplifiers is discussed and analysed, inferring some useful design guidelines.By a simplified active device model,the effects of the amplifier harmonic loads on the intermodulation distortion are investigated and experimentally validated showing the IMD3 performances of four hybrid amplifiers,designed using different harmonic manipulation strategies (i.e.different harmonic input and output terminations).
